Honestly, 

I'm really disappointed.
Seven suspects, we have four of them who are really interesting: Bret Stiles, Brett Patridge, Bob Kirkland and Ray Haffner. Then, we have three boring characters, Smith, Bertram and McCallister. 

It's difficult to believe but the four interesting suspects are dead and we have just the three boring suspects. It has been something difficult to understand, because with the huge final on the fifth season they had a lot of possibilities. I'm just hopping that Bret Stiles or Brett Patridge dead's has something hidden.   

Watching the promo of the 6x08 chapter ("Red John"), I realized that Gale Bertram and Sheriff McCallister can't be Red John. Do you imagine? The most important serial killer running, breaking windows like a vulgar thief...?  I don't think so. 

Red John has been a genius, Red John has been surprising us during all this time. Please, I hope he is not going to be killed so easy. I want to be fascinated about this last red john's era chapter. I want to see how Bret Stiles or Brett Patridge are still alive, please tell us something different. 

Come on, six years looking for Red John, I don't want to see how he is killed by a bullet in a church. I want to see Red John tricking Jane a last time, I want to see how we have all been tricked. If Bertram, McCallister or Smith are Red John the best thing we can do is consider the third season as the last one. 

The other day a friend told me, imagine Jane killing Bertram, thinking that Red John is dead. And then, Red John kills someone else, so we see Patridge being Red John and Stiles as his father. It would be fascinating!!

I know the most probably is that I'm wrong. But I still hope Bret or Brett to be Red John.
